A nurse in an emergency department is reviewing a client's ECG reading.

Which of the following findings should the nurse identify as an indication that the client has first-degree heart block?

Prolonged PR intervals.

Nondiscernible P waves.

More P waves than QRS complexes.

No correlation between P and QRS waves.

Answer and Explanation

The Correct Answer is A

First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.

Correct Answer is A

Explanation

The nurse should provide the client with a short-handled teacher.

This can help the client to reach and grasp objects without having to overextend or strain their unaffected arm.
Choice B is also correct.
The nurse should place a plate guard on the client’s meal tray.
This can help prevent food from spilling off the plate and make it easier for the client to eat with one hand.
Choice C is wrong because reminding the client to use a cane on his left side while ambulating could be unsafe as the client’s left side is affected by hemiplegia.
Choice D is wrong because positioning the bedside table on the client’s left side could make it difficult for the client to reach items on the table.

A. Sardines. B. Apricots. C. Scallops. D. Nuts. E. Liver.
